OTTO I-I. FITZKE, OF OWATONNA, MINNESOTA.

PIPE-VISE.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed January 12, 1916. Serial No. 71,789.

To all whom it may concern:

Be it known that I, OTTO H. FITZKE, a citizen of the United States, residing at Owatonna, in the State of Minnesota, have invented certain newand useful Improvements in Pipe-Vises, of which the following is a specification.

This invention relates to improvements in pipe vises, one object of the invention being the provision'of a vise in which the lower pipe engaging members instead of being stationary are revoluble, so that the pipe may be rotated, thus permitting the pipe to revolve instead of making it necessary to push the pipe cutter over the pipe as is usual.

A further object of the present invention is an open side vise having two rotary jaws with means for locking the jaws in adjusted position, the main locking aw being provided with a plurality of antifrictional pipe engaging members so that the pipe can be rotated upon its axis but not be per mitted any longitudinal movement.

A still further object of this invention is to produce a vise that will hold flanges and other fittings as well as pipe, and which will support any length of pipe due to an adjustable rear support carried by the base of the vise.

In the accompanying drawings :Figure 1 is a front elevation of the vise. Fig. 2 is a top plan view showing the rear support. Fig. 3 is a rear elevation. Fig. at is a detail view of one of the gripping rollers and its locking member. Figs. 5 and 6 are detail views of various parts.

Referring to the drawings, the numeral 10 designates the base, which is provided with the two parallel tracks 11, upon which are adjustably mounted the standards 12 of the rear pipe support. J ournaled in these standards is the roller support 13, while pivoted to the upper end of one standard at one end is the holding chain 14,, whose other end is provided with the standard engaging member 15, so that various diametered or sized pipes may be accommodated.

At the forwardend of the base is carried the lower portion 16 of the main frame of the vise, the upper member 17 being swingingly connected as at 18, while the locking bolt 19 connects the other side to the lower portion 16. Mounted in the upper member 17 is a hand operated feed screw 20, whose lower end is connected to the movable member 21, which in turn is provided with the antifrictional pipe engaging rollers 22 in the lower concaved face thereof.

Two corrugated rollers 23, having journaling pintles 24, are mounted in the lower member 16, these rollers intermediate of their ends being provided with gear teeth 25, whose outer ends are within the periphery of the roller, so that the locking member 26 may be operated to engage and release the gear 25 and thus lock or release its roller. By this means the rollers when receiving a pipe may permit the pipe to be rotated, or may lock the pipe from rotation.

l/Vhat I claim as new is 1. A pipe vise, including a base, a rear pipe support longitudinally adjustable upon the base, a two-membered frame at the forward end of the base, a manually controlled jaw mounted in the upper member of the frame, two corrugated pipe gripping rollers mounted for rotation in the lower member of the frame, and cooperable means carried by each roller and the frame for locking the roller from rotation.

2. A pipe vise, including a base, a rear pipe support longitudinally adjustable upon the base, a two membered frame mounted at the forward end of the base, a manually controlled jaw mounted in the upper member of the frame, two gripping rollers ournaled in the lower member of the frame, each roller being provided with a corrugated surface interrupted intermediate of its ends with a gear of lesser diameter than the roller, and a locking device for engaging the gear of each roller.

In testimony whereof I aflix my signature.

OTTO H. FITZKE.
